Apparatus for determining the level of material 13 in a bin 12 comprises a probe 14 which is lowered by a cable 15 into the bin, contact between the probe and the material being sensed by the change in current taken by the drive motor 22. This is used to reverse the motor and raise the probe 14 until a counterweight 21 at the other end of cable 15 reaches a limit stop 31, when motor 22 is again reversed to lower the probe into the bin again. This cycle is continuously repeated. A selsyn transmitter 24 is mechanically coupled to motor 22, and electrically coupled to an indicator 28, which thus indicates the position of probe 14 continuously or only at the end of the inward travel. The control circuit, containing alarm devices, is described Fig. 2 (not shown).

Title: Improvements in or relating to the production of pattern effects on materials made of or containing cellulose esters or ethers
IPC: D06P5/15
Filed: 1929-10-26
Abstract: Printing; cellulose esters or ethers, dyeing; regenerated celluloses, dyeing.-White or coloured discharge or resist effects are obtained upon textile materials made of or containing cellulose esters or ethers by the application of compounds of reducing metals, e.g. stannous or titanous compounds, such as stannous or titanous chloride, in the presence of compounds containing the thiocyanate radicle, e.g. ammonium thiocyanate or alkali or alkaline-earth thiocyanates.  The discharge may be assisted by the presence of acids, especially organic acids, e.g. citric or tartaric acid, and/or swelling agents.  Thus acids may be incorporated in the discharge preparations or the fabrics may be pretreated therewith as described in Specification 334,518, [Class 15 (ii), Dyeing, Processes &c. for]. As suitable colours for incorporation in the discharges are specified the resistant basic dyes of the di- and tri-arylmethane, azine, oxazine, and thiazine series.  The fabric may be coloured uniformly or locally with a suitable dischargeable dyestuff and printed or otherwise locally treated with the reducing metal compound in presence of a thiocyanate, or it may be treated locally with a preparation containing the metal compound and a thiocyanate and treated subsequently with a suitable dischargeable dyestuff.  The invention is applicable to materials containing cellulose esters or ethers in admixture with other fibres such as cotton, wool, silk, or regenerated celluloses, with or without suitable colouration of the non-ester or non-ether fibres.  The following examples are specified. (1) A fabric woven from cellulose acetate yarns and dyed with p-amino-benzeneazodimethylaniline, diazotized on the fibre and coupled with b -oxynaphthoic acid, is printed with an aqueous paste containing gum arabic, auramine, stannous chloride, potassium thiocyanate, and citric acid, and steamed or aged, to obtain a brilliant yellow pattern on a black ground.  (2) A similar fabric, similarly dyed, is printed with a similar aqueous paste containing methylene blue as the dyestuff, steamed or aged, and treated in a soap bath containing sodium perborate to obtain a greenish blue pattern on a black ground.  (3) A similar fabric dyed with a dispersion of the dyestuff 5-nitro-2-anisidine-->dimethylaniline is printed with a similar aqueous paste containing malachite green as the dyestuff, and steamed or aged to obtain a brilliant green pattern on a red ground.  (4) A similar fabric dyed with cellit blue R, 5-nitro-2-anisidine-->ddimethylaniline, and 4-chlor-2-nitro-diphenylamine is printed with a similar aqueous paste containing methyl violet 2B as the dyestuff, and steamed or aged to obtain a bright violet print on a brown ground.

A feed Toll 20 for advancing a yarn under constant, uniform tension and speed, as may be required in supplying yarn Y to a falsetwist crimping machine, is associated with a pinch roll 46 which is pivoted about horizontal and vertical axes and biassed by a spring 45 so that it automatically adjusts, by a dual pivotal movement, to nip, under constant pressure, the yarn traversing across the roll 20. A detector initiates disconnection of the feed rollgear 22 from its driving gear 10 when the yarn is interrupted. Yarn passing over a bail 60 normally prevents clockwise rotation of an adjustably counterweighted, roller-arresting element 52 around a stud 48, supporting a coiled portion 54 thereof. When the yarn breaks or. is exhausted,. the unbalanced weight of element 52 causes it to rotate so that a bent portion 58 engages teeth of gear 10 which thereby rocks arm 16 to an inoperative remote position whereat gears 10 and 22 are held out of meshing engagement and a pin 59 prevents passage of yarn from source between rolls 20 and 46.
Patent GB-486097-A (GB)
Title: Process for the manufacture of water-soluble azodyestuffs
IPC: C09B69/00
Filed: 1936-11-30
Abstract: Water-soluble azo-dyes are obtained by coupling diazo compounds with aromatic amines in which one hydrogen of the amino group is substituted by a hydroxyalkyl radicle which is esterified to an acid ester of phosphorous acid, and the other is substituted by an alkyl radicle.  No further acid groups are present.  The coupling components are obtainable by reacting an N - hydroxyalkylated aromatic amine with a phosphorus trihalide in an indifferent solvent and subsequently hydrolyzing to the mono-ester of phosphorous acid. Alternatively, dyestuffs containing, in the coupling component an N-hydroxyalkyl-alkylamino group may be esterified as above.  The products dye wool, silk and cellulose acetate artificial silk, especially cr<\>zepe fabrics of the latter.  In examples (1) to (3) and in a table, the following amines are specified as diazo components: p - nitraniline, 2 - chloro - 4-nitraniline, 2.4 - dinitraniline, 6 - bromo - 2.4-dinitraniline, 2-amino-6-ethoxy-benzothiazole and 1-aminonaphthalene-4-methylsulphone; and the following as coupling components: the acid phosphorous acid esters of N-b -hydroxyethyl-methyl-aniline, N-b -hydroxyethylethyl - aniline, N - n - butyl - b -hydroxyethyl - 3-toluidine, N-n-butyl-b -hydroxyethyl-cresidine, and N-b -hydroxyethyl-ethyl-3-toluidine. Yellow, orange, red, violet and blue shades are obtained on acetate artificial silk from a Glauber's salt bath.  In example: (4) the dry dyestuff, p-nitraniline --> N-b -hydroxyethyl-methyl - aniline, is dissolved in methylene chloride and added to phosphorus trichloride; the mixture is heated to boiling for some time, whereupon the esterified dye is precipitated.
